Year and model shown as prefix to engine number. For example 8-T-33445 is a 1938 Speed Twin (later identified as "5T" instead of just "T". Frame prefixes were-th"for early Speed Twin. 'TF' for the TI00 and later 39/40 Speed Twin. 1940 to 1949 Models 1946 from 72000 prefixed as before 1947 from 79046 prefixed as before 1948 88864 to 102235 TFI 5001 to TF2500 1949 102236 to 113386 TF25001 to TF33615 Year shown in engine number prefix with two figures. For example 40-5T-26445 is a 1940 Speed Twin. This practice followed religiously and some single prefixes may appear on postwar models. Frame prefixes were 'TL" for the 3T up to 1948 and TC for 1949. TR5 for 1949 was TC followed by a 'T" after the actual number. All other frames were TF. TR5 models did not have seperate number seriers but ran concurrently with all other models. I.E. 112671 was last '49 TR5 and I1 3386 the last '49 5T. Note: All Grand Prix T-1 00's have leter 'R" suffix following engine and frame numbers. TR5 models had seperate number series; engines from 101001 to 106424, frames from TC11001-T to TC13107-T. By 1950 frame and engine numbers were matching.
